Who and why is hammering nails into the asphalt everywhere

Far from all things road related, a person can be genuinely surprised by things that seem obvious to a professional. One of these is “carnations” in the roadbed, which constantly catch the eye on the sidewalks and adjacent areas.
Let’s start with the fact that the described artifacts are not exactly nails, but the so-called dowels, with the help of which structures are usually attached to the walls. And we are talking about dowels that are not screwed in with a screwdriver, but are driven into any surface with a special mounting gun – even the most durable concrete. Sometimes we see that only a “carnation” hat sticks out of the asphalt. Sometimes a bright spot is applied around it with paint. Sometimes the dowel is driven into the center of the cross, painted with the same paint. And it happens that a metal cork from a bottle is “sewn” to the asphalt.
What does all this mean and what prankster needs it? Men whose childhood passed during the Soviet era, at the words “plugs in the asphalt” will surely remember the “innocent” fun of the children of those years. Then there was simply nowhere to buy a firecracker, and the thirst for adventure on the young “fifth point” required the organization of something firecracker. One of the recipes of this kind implied the presence in the pocket of the “actor” a box of ordinary matches and required, among other things, to hammer a dowel into the asphalt.
Such entertainment, fortunately, is alien to modern children, so we will not consider this version. According to conspiracy theories, the appearance of dowels in the asphalt can be considered traces of the activity of enemy saboteurs, leaving traces on the streets of cities that they need for something mysterious and espionage.
In fact, the phenomenon of “plugging” in asphalt has a much more interesting explanation than all of the above. They indicate air defense points! The abbreviation stands for the point of “planned elevation justification” on the ground. They were created during the geodetic survey of the site. The exact value of the surface height above sea level is strictly bound to the coordinates of each of these points. They form the plan of the area. Workers are guided by the heights and their differences between the points marked with dowels when constructing the roadway. And builders “attach” projects of buildings and structures to it.
The problem is that when changing the old asphalt, the dowels are mercilessly picked out and the surveyors are forced to place the same air defense points over and over again. This makes it seem that the dowels they mark constantly appear on the pavement.
